SyntaxError:语法无效

Question

我只是按照Scrapy文档写了我的第一个蜘蛛。

dmoz_spider.py:

import scrapy
class DmozSpider(scrapy.Spider):
    name = "dmoz"
    allowed_domains = ["dmoz.org"]
    start_urls = [
        "http://www.dmoz.org/Computers/Programming/Languages/Python/Books/",
        "http://www.dmoz.org/Computers/Programming/Languages/Python/Resources/"
    ]
    def parse(self, response):
        filename = response.url.split("/")[-2] + '.html'
        with open(filename, 'wb') as f:
            f.write(response.body)

然后当我运行它时，我得到了以下错误:

SyntaxError: invalid syntax

我怎么解决它?在Python 2.7-32位运行?
